A man who got lost/stranded on some pack ice on the frozen North Sea was spotted and rescued after he repeatedly used his camera flash as a signaling device. The catch? The flash bursts were spotted by a woman who was hundreds of kilometers away, and watching the sunset on her computer in southern Germany!

That, and the fact that German society revels in noticing others doing weird things... keeps everyone nicely on the safe and narrow path. Not in Berlin of course, where you're required to complete Hedonism training before you're allowed out into the general population
